Integrated management of sesbania rostrata and urea nitrogen in rice under a rice-rice cropping system

Abstract

An investigation was undertaken at the farming systems research site, Bagherpara, Jessore, to study the effects of green manuring (Sesbania rostrata) followed by five rates of N application on the grain yield of T. aman rice and physical and chemical properties of soil. Grain yield of rice increased significantly after green manuring. Application of a varied rates of N further improved the yield. Addition of 30 kg N/ha after green manuring produced almost similar grain yield to that of 90 kg N/ha without green manuring. Availability of N, P and K in the soil and the water holding capacity of the soil increased after green manuring.
